Spirulina is a type of blue-green algae, which are microscopic fresh-water organisms, also known as cyanobacteria. The green pigment of spirulina comes from chlorophyll, while the blue comes from a protein known as phycocyanin.

Spirulina is mostly made up of proteins. These proteins are complete because they contain all essential amino acids making them similar to animal protein. These proteins however do not contain saturated fats, or antibiotics found within some form of meats.

Spirulina is a good source of trace minerals, some vitamins, bioflavonoids, and other phytochemicals.

Within spirulina is a high content of vitamin B12, which makes it a great source of the vitamin for vegans and other strict vegetarians likely to be deficient in vitamin B12.

A small percent of spirulina species contain significant amounts gamma linolenic acid (GLA), which has anti-inflammatory and antiproliferative properties. For this reason spirulina is potentially beneficial for people who suffer from rheumatoid arthritis and diabetic neuropathy. It may also play a role in lowering plasma triglycerides and increasing HDL cholesterol.

Spirulina is a also useful in the absorption of both iron and zinc. One study performed on rats found that when given spirulina, they had equivalent or better absorption than those given a ferrous sulfate iron supplement. A study of zinc deficient children concluded that those taking spirulina had a much better response to those taking zinc sulfate, and had fewer side effects.

Consumption of spirulina may also lower cholesterol, serum lipids, and low-density lipoprotein (LDL) cholesterol by a small but significant percentage. In a study involving a group of men with high cholesterol who were given 4.2 grams of spirulina per day, a 4.5% decrease in cholesterol was evident after just one month.

You can find spirulina supplements in a wide array of forms including powder, flakes, capsules, and tablets.

* Important note: The recommended doses are for those over age 18. Always check herb and vitamin use with your child’s health care practitioner prior to administering them.
